Malachi Johnson, 4, died Friday after falling from his family's Co-Op City apartment in the Bronx.

The Bronx balcony where a 4-year-old tumbled to his death Friday was supposed to be sealed off five days earlier for city-mandated repair work, according to notices sent to residents.

"We all got notices that we were supposed to have our balconies cleared on June 6," Maria Centeno-Rosario, 49, said Saturday. "They said the balconies would be sealed."

Malachi Johnson plunged 23 stories to his death Friday night as he played on his terrace at a Co-op City building. Police sources said his mother, Denise Warner, was in the shower and that the boy may have fallen off a chair found on the balcony.

But Sclafani could not say whether Malachi's balcony was among those found to be unsafe during the inspections.

Inspectors who looked at the balcony after Malachi fell found no structural problems, Sclafani said, adding, "It appears at this time that the accident was not related to the condition of the balcony."

Butnotices received recently by tenants from RiverBay Corp., the management company, warned them that contractors would seal the balconies and begin repairs.

"If everything would have been sealed like they said, this wouldn't have happened," said Audrey Butler, a 47-year-old nurse.

RiverBay Corp. did not respond to messages left at a weekend number for the company.

Tenants like Enis Johnson, 41, were angry that the work hadn't been completed.

"Nothing around here gets done on time, so I just ignored it," he said.

Other residents complained that there was a 6-inch gap between their balcony's railing and the building.

"I would never let my kids out on the balcony," longtime resident Luc Valentin, 61, said.

A small memorial made up of a toy fire truck, candles, a toy hammer and a stuffed green frog was set up where Malachi died.
